To all wimmt may concern.'

Be it known that I, ARTHUR A. JOHNSON, a citizen of the United States,residing in Lyndhurst, in the county of Bergenand State of New Jersey,have invented certain new and useful Improvements in Type- WritingMachines, of which the following is a specification. Y I

This invention relates to .an improvement in typewriting machines, andmore particu-A larly to a fan-fold attachment for making manifold copies'continuously., using the same set of carbon sheets. -This case is animprovement on' my application, No. 17 6,488, led June 23, 1917, and onthe patent .to "vii/'ernery and` Smith, No. 1,132,055, dated March 1 6,1915. A

@ne of the objects of the invention is to providev improved means forenabling the same sheets of carbon to be used repeatedly with a numberof successive sections of a fan-fold web, so that the sheet and carbonleaves will b e always assembled relatively to each other ina pack. Asone portion of each carbon sheet is worn out, afresh. portion may bedrawn on to replace it. Thisl avoids the necessity of frequently takingapart the assembled pack of interleaved carbon sheets and web.

For the purpose of facilitating the use of the continuous supply ofcarbon with the continuous fan-fold web, the plies of the web arethreaded between a series of diagonal guides or warping bars, whichdirect the carbon sheets from the side into line with and between thelayers of the fanfold web. The supply rolls from which the carbon sheetsare drawn are mounted on the table carriage on which the bars or guidesare mounted. This table carriage moves f orward with the advancingline-space rotation of the platen. Thus, thecarbon sheets and theirsource of supply -keep pace with the l movement of the web. The carbonsheets are Vmoved rearwardly relatively to. the worksheets, by pushingthetable-carrlage rearwardly. Tn doing this, the carbon sheets are y notordinarily withdrawn from their rolls, as only that portion which isbetween the folds of the work-sheet web is used. Locking or clampingmeans is provided for premay be released when it-is necessary to re newthe carbon sheets between the folds of the work-sheet web.

The platen is raised, as more particularly described in theabove-mentioned patent, for straightening out the bend in the assembledwork web and`- carbon sheets, to enable the relative displacement orspacing between the same.

Other features and advantages will hereinafter appear.

In the accompanying drawings, j

is pivotally mounted by means of a swinging frame 3 on the platen frame4. The platen frame 4 is mounted on a carriage 5, which A platen 1 issupported by an axle 2, which platen axle 2, but not rigidly connectedtherev to. To connect the platen axle 2 with the knobV axle9, there isprovided on the platen axle a gear 10 meshing with a broad pinion 11,which, in turn, meshes with a gear 12 'of the knob. axle 9, ofsubstantially the same. gear l0. In this way, the' diameter as therotation ofthe knob 7 and the movement of the line-space lever 8 areindirectly transmitted to the platen 1. This arrangement enables theplaten 1 tobe raised from its locked in a typewriting position lby aspring latch' 14.

'carbon sheets may be straightened out, so

that the carbon sheets can be readily slipped along the work sheets forspacing purposes. To raise the platen in' this way, there is provided ahandle 13, which is normally The work-sheet orweb, indicated at'15, isin the present case of fan-fold type, and is shown to consist of velayers or folds which are connected in a continuous series at their sideedges. This fan-fold web, as a whole, is in a continuous strip which mayor may not have printed forms thereon to lbe torn off successively astypewritten to form separate bills or letters. The web 15, in order tohave the matter typewritten on 'the exposed layers take on the underlayers to form duplicate copies, must be interleaved with carbon sheets16. There are four of these tar-Y bon sheets shown, one for each of theunder layers of the fan-fold web. To `direct the carbon sheets 16 from asource of supply off to one side to a position between the layers orfolds of the web 15, there are provided a work-sheet web and the carbonsheets in' a line-space direction, so as to keep pace with the rotationof the platen. .The table 19 also keeps pace with the letter-spacemovements of the platen l by. being mounted on an extension 20 carriedby the typewriter Acarriage 5. This extension is supported by a roll 21running on a rail 22, provided on a bracket 23, extending rearwardly'.rom the typewriter frame. The mounting of the traveling table 19 maybe of any suitable character, as by means of wheels 24, traveling inrails 25 provided by the extension 20. Although the carbon sheetsmay-be. used repeatdly with a number of successive sections oie thework-sheet web, in the' course of time the vorn out.

rolls 26 are arranged parallel to the direction of travel of the table19, so that the car bon sheets extend from theserolls to the guides 17,and then are warped to extend inA the direction of travel of the'table19 and also in theV direction ofthe travel of the web 15.v The rolls arearranged two on each side, the outer ones being slightly 4depressedbelow the inner ones, as illustrated in Fig. 3, s o as to enable thelower carbon sheets to clear Ythe inner rolls. The rolls 26 may bedetachably mounted in bearings 27, so that when all the carbonpaper onthem is used up, they can be replaced by fresh rolls. For this purpose,the bearings 27 are open bearingsclosed by springs 28,- which engage theaxles of the rolls 26.

In order that the carbon paper may not be drawn from the rolls 26 untilit is desired to renew that portion of the carbon sheets whichis'between the folds of the web, there are provided paper locks. orclamps -29 and 30, one for each pair of canbon rolls 26. These -clampseach comprise a stationary jaw 31 and a pivoted jaw 32. Normally, thepivoted jaws 32 are'held in the position of Fig. 3 gripping :thecarbon-sheet strips between them. Y This is done by providing each ofthe swinging jaws with a pin 33. These pins extend into cam slots 34provided in levers 35 and 36. The levers 35 and 36 are connected by alink 37, so as to move in unison, 'thereby' closing o r opening thevclamps 29 and 30 in unison.

.is provided with a grip 38, whereby the lev- The lever 35 ers 3'5 and36 maybe manipulated to open and close the clamps 29 and 30. The camslots 34 are 'formed with end dwells (see 3 and 5) so that they willautomatically swing the pivoted jaws 32 according to the direction ofmovement of the levers 35 and 36, and the dwells will lock, them intheir open or closed position.` 1n this way, the'supplyof carbon paperis not drawn on until needed, although the movement of the work-sheetweb relative to the carbon sheets would tend to draw the carbon paperfrom the roll.' Y

Y The utility of the devicev will be readily understood when taken inconnection with the above description, Starting 'with the .assembledpack of work-sheet web and carbon sheets, in position on the platen tobe written on, the bill or other piece of work is typewritten line -byline. The web and carbon sheets will advance line by line with theline-space movements of the platen. The web and carbon sheets will drawthe" traveling table 19 along with them, and there will be noappreciable relative movement between the table and either the web orcarbon sheets, the latter being locked by the clamps 29 and 30.

lFehen a bill l0r other piece of work is completed, the platen 1 israised by means of the handle 1.3, yso as to straighten out the bend 1nthe assembled pack of paper. The

table 19 can then be forced rearwardly by 4portion of thework-sheetl-Web. This may be determined in `any suitable mannen as bybringing the leading edge ofLthe worksheet Web into engagement with anadjust- The platen l'canthen be returned to its typewrlting position androtated .either by the knob 7 orthe line-space lever 8, to bring theinitial line to be Written on in register with the printing point of thetypewriter. This will carry the table 19, the web 15 and the carbonsheets 16S-.along in I unison. When the bottom edgeof the completedpiece of work-has come in register with' a knife 41, the piece of workmay be severed from the continuous strip of web. The new piece ofWorkfcan be written line by line as before, and, when completed, arelative spacing between the carbon sheets and the work-sheet web may bemade and the operation repeated over and over again, thus obtalmngdupllcate copies of a number of successive pieces of work, such asbills, in a continuous manner.

When the carbon sheets between the folds `Action agam, soas to preventmore carbon paper than isneeded from being unrolled. The used portion ofthe carbon sheet which is to be discarded wi1l be cut off by' the knife41, when the partlcular bill or letter with which it is lnregisteris-severed the body of the web.
